Product Introduction

The AS400 communication card provides contact closures for remote monitoring
your UPS. To meet different application requirement, the AS400 card is capable of
selection the status of the dry-contact signal (active close or active open) by setting
jumper. This suitable applications are listed below:

IBM Server, Personal PC & Workstations equipments

Auto-controlled industrial equipment & communication applications

Step 1: Remove cover of Intelligent
Slot on the rear panel of the UPS.

Cover of
Intelligent Slot

Step 2: Insert AS400 card into Intelligent
Slot.

Step 3: The cover of AS400 should attach
close to the rear panel. Using screwdriver,
secure the AS400 to the UPS chassis with
2 screws.

Step 4: Use the 9-pin communication
cable to connect UPS and equipment to
implement the remote monitoring and
control.

Note: It’s required to retain the DC current lower than 6mA. Otherwise, it’s
necessary to add one resistor within DC current limitation in the serial loop of
Remote Shutdown. (e.g. 2K resistor with at least 0.1W rating power). Refer to
diagrams in Application.
